- this is to help more users get the benefit (by default) and perhaps circumvent the common mistake of setting EKF2_HGT_MODE to range sensor
- this should be safe to enable as the range aid defaults are fairly conservative (max horizontal velocity 1 m/s, and range aid gate 1 SD)
statfs accesses the file-system and can be blocking for an extended period. Since the SD card check is part of the preflight checks in the main thread of commander, it could block its execution and cause various issues. The SD card is only mounted in rcS during boot so the state will not change after the first check.
- Source processing now happens on original source files:
- processing to line-by-line
- required overhaul of regex match patterns + processing
- pros:
- enable tracing of ambiguous parsing sites -- reports (module, file, line-number, line-contents)
- simplifies code
- reduces computational complexity
- cons:
- certain declarations are harder to parse: multiline declarations
- refactors:
- added specific subclasses for each: Publications, Subscriptions, Ambiguities
- added a "Scope" class to represent either a module ('ModuleScope') or a library ('LibraryScope')
- regexes:
- added cases for C++-style classes
- expanded C++-style regex cases to accommodate templates
- `ORB_ID::` is accepted wherever `ORB_ID(` is accepted
- adds 'orb_copy' regex to the subscription cases
- emit ambiguous-line warning for declarations with `ORB_ID` on the same line
- emit ambiguous-line warning for `ORB_ID` with a declaration on the same line
- changed 'module whitelist' to 'scope-whitelist'
- whitelist may now apply to libraries
- libraries are optionally merged with their depending modules (but not by default)
- may be merged with their depending modules with the `--merge-depends` cli flag
- eliminates some redundant 'special-case' handling code
- debug output
- raises exception and aborts if a topic is found outside of a scope
- debug output is now printed & filtered with the python 'logging' standard module
- alphabetizes topic output in debug logging
- fixes debug output if package dependencies are missing
- now warns on ambiguous matches
- prints a list of ambiguous source sites (aka warnings) on completion
- (still) emits a warning if we find ORB_ID outside of a scope
- adds warnings if any of the source paths are invalid
- do not emit debug output for modules outside of the module/scope whitelist
- Expand script's CLI parameters
- added 'none' output options: undocumented debugging option to silence file output while debugging
- added the `--merge-depends` cli flag -- merges output of modules & their dependee libraries
- the ekf2 frontend typically runs in the background for up to 30 seconds waiting for all instances to appear, but this isn't supported by the legacy posix launcher
This is to avoid race condition with the yaw emergency estimator having
the same trigger delay of 1 second. Commander will now give more time to
EKF2 to reset itself before switching to altitude mode.
